x86/platform/UV: Add UV4 addressing discovery function
UV4 requires early system wide addressing values. This involves the use
of the CPUID instruction to obtain these values. The current function
(detect_extended_topology()) in the kernel has been copied and streamlined,
with the limitation that only CPU's used by UV architectures are supported.
